Thanks for the reply.
I used the cat command this time, the result is not great.
In my test, file hadoop003.log is cached while hadoop010.log is not cached.
-bash-4.1$ /hadoop/hadoop-2.3.0/bin/hadoop fs -ls
-rw-r--r-- 3 hdfs hadoop 209715206 2014-03-06 18:14 hadoop003.log
-rw-r--r-- 3 hdfs

Hello,
It looks like the HDFS caching does not work well.
The cached log file is around 200MB. The hadoop cluster has 3 nodes, each
has 4GB memory.
-bash-4.1$ hdfs cacheadmin -addPool wptest1
Successfully added cache
hi, have you solved your problem? i have the same problem. it seems that
the cache behavior has not been triggered.
